“…Like TCs, PTTs tend to occur after the age of 60, 10,13–15 but they have been reported in individuals as young as 18 years 17 . PTTs range in size from less than 1 to 10 cm 13 although lesions up to 25 cm have been reported 26 . The clinical differential diagnoses for PTT includes epidermoid cyst, keratoacanthoma, SCC, pilomatrixoma, sweat gland tumors, dermatofibrosarcoma protuberans, cylindroma, basal cell carcinoma, and angiosarcoma 13,14 …”

“…PTC presents as a solitary nodulocystic lesion, usually ranging in size from 1 to 10 cm in diameter, and very rarely reaching up to 25 cm in size. 53 Occasional patients may develop multiple tumours. 54 PTC is believed to originate from a pre-existing trichilemmal cyst.…”

Skin adnexal neoplasms comprise a wide spectrum of benign and malignant tumours that exhibit morphological differentiation towards one or more types of adnexal structures found in normal skin. Most adnexal neoplasms are relatively uncommonly encountered in routine practice, and pathologists can recognise a limited number of frequently encountered tumours. In this review, the first of two, the normal histology of the skin adnexal structures is reviewed, and the histological features of selected but important benign and malignant tumours and tumour-like lesions of pilosebaceous origin discussed, with emphasis on the diagnostic approach and pitfalls in histological diagnosis.

“…4 Apocrine carcinomas manifest as non-tender single or multiple, firm, rubbery or cystic masses with red to purple overlying skin. 5 Tumour cells are PAS (periodic acid-schiff stain) positive due to glycogen granules and diastase resistant Eccrine gland carcinomas possess no distinctive clinical features making diagnosis by gross appearance virtually impossible. They usually manifest as non-tender, subcutaneous nodules, primarily in elderly individuals4.…”

Malignant adnexal tumors: a rare case of cutaneous malignancy

2017

View full text Add to dashboard Cite

Skin adnexal tumours (SAT) are a large and diverse group of benign and malignant neoplasms, which exhibit morphological differentiation towards one of the different types of adnexal epithelium present in normal skin: pilosebaceous unit, eccrine and apocrine. In present case, a forty-five-year-old female patient presented to us with a solitary erythematous swelling over the left chest wall since two years, which was approximately 3 × 3 cm in size, slowly growing to its present size of 10X5 cm, painless, hard in consistency with smooth erythematous surface, non-mobile and not associated with discharge or axillary lymphadenopathy.
